Flag wrong times from GPS week rollover issue

[barbeau]

Summary:

Requested by a user:

using an aging samsung s4 on lollipop - i've run into the "gps week number rollover" issue and the time and date logged by your app are stuck in the year 1999 and my time's off as well. i know it's an old phone, but still...is there any chance you can look into this and perform a correction in software?
it looks 'regular'... apart from right now in the u.k where i am it is 3:26pm and your app top right will display 4:26pm. at first i thought i had a g.m.t/b.s.t timezone issue but another of my apps i use for motorsport confirmed the same. i did a quick log of nmea output and was "somewhat surprised" to see i'd timewarped back to last century... july 1999 to be exact. galaxy s4 gti9505 on lollipop

The issue of wrong times from the GPS week rollover issue has come up on the Google Group before:
https://groups.google.com/forum/#!topic/gpstest_android/AXHaBqdKNnQ

I'd like to at least flag the time as red and maybe add an error note to the device info page (#313) to indicate that there is a problem.

Steps to reproduce:

Run app on device with GPS rollover issue (for example, see https://www.verizonwireless.com/legal/notices/global-positioning-system/)

Expected behavior:

Flag that time is wrong and describe why

Observed behavior:

Time appears normally, just a bit off
